CC16-HNE is Associated With Mortality and Pulmonary Hypertension in IPF
September 7, 2024
A marker of human neutrophil elastase mediated club cell secretary protein-16 degradation in (CC16-HNE) is associated with mortality and pulmonary hypertension in idiopathic pulmonary fibrosis
Introduction
Idiopathic pulmonary fibrosis (IPF) is characterized by epithelial injury, fibrosis, and an aberrant immune response. Club cells are essential for lung homeostasis by repairing the injured epithelium and secreting the anti-inflammatory club cell secretory protein-16 (CC16). Additionally, activated neutrophils release human neutrophil elastase (HNE) during inflammation. Our aim was to investigate if serum measurements of CC16 degradation by HNE (CC16-HNE) were related to IPF mortality and pulmonary hypertension (PH).

Conclusion
Low serum CC16-HNE at baseline was associated with increased risk of mortality and a PH complication in IPF. These results indicate that a neutrophil immune response and degradation of CC16 is relevant for disease outcome. CC16 degradation by HNE could serve as a prognostic biomarker for IPF and diagnostic for a PH complication.
